Car parking space needed

I live in Coin St and need a lock up garage or a off road space somewhere to park my car. I currently rent a space in the ACP carpark in the National Theatre, but it is costing me a fortune. I would need somewhere buy the end of september.
I use the car only at weekends and so somewhere in the vicinity or walking distance of Coin St would be great. Any offers?

I was interested to find, when checking a dictionary recently, that "need" doesn't imply lack of an essential thing, but rather lack of something that you just would like to have. Thought that was interesting. Sorry for off topic posting.
